SPORES 3-4 x 1.5-2 microns, smooth, inamyloid, thin-walled; BASIDIA 4-spored, 6-8 x 3-4 microns, cylindric to subclavate, developed from SUBHYMENIAL HYPHAE in cymose clusters through progressive proliferation from clamp connections, sterigmata upright, slender, slightly arcuate; CYSTIDIA 25-45 x 2.5-3.5 microns, extending two thirds of their length beyond the hymenium, cylindric or narrowly obclavate, somewhat flexuous [wavy], thin-walled, unencrusted; SUBICULUM made up of hyphae 1-2 microns wide, fine, horizontal or irregularly interwoven, thin-walled, with clamp connections, walls usually heavily encrusted with crystals, (Jackson)
